  • Composition and process for bonding rubber to metal
    Patent number: 5028654
    Abstract: The invention seeks to improve the preheating resistance and high temperature resistance during vulcanization of a cement for the vulcanization of rubber onto metals.

  • Two stage method for operating autodeposition bath
    Patent number: 5011715
    Abstract: An autodeposition bath for coating steel and similar metals is operated initially with a low content of dissolved iron and at a high oxidizing potential. After the iron content has increased beyond a specific level, such as 1.5 g/l, the oxidizing potential is reduced. This permits continued satisfactory operation of the bath with lower rates of iron accumulation in the bath, so that the need for bath stabilization by removing dissolved iron is deferred.
